Data Structures Algorithms Online Quiz
Following quiz provides Multiple Choice Questions (MCQs) related to Data Structures Algorithms. You will have to read all the given answers and click over the correct answer. If you are not sure about the answer then you can check the answer using Show Answer button. You can use Next Quiz button to check new set of questions in the quiz.
Q 1 - A procedure that calls itself is called
Answer : C
Explanation
In recursion, a procedure calls itself, either directly or by calling a procedure which in turn calls it.
Q 2 - Which one of the below mentioned is linear data structure −
Answer : D
Explanation
All mentioned data structures are linear in nature.
Q 3 - Find the odd out
A - Prim's Minimal Spanning Tree Algorithm
B - Kruskal's Minimal Spanning Tree Algorithm
Answer : C
Explanation
Floyd-Warshall's All pair shortest path Algorithm uses dynamic programming approach. All other mentioned algorithms use greedy programming approach
Q 4 - What could be the worst case height of an AVL tree?
Answer : C
Explanation
Worst case height of an AVL tree is 1.44 log n
Q 5 - Which of the following has search effeciency of Ο(1) −
Answer : C
Explanation
A simple hash table has the Ω(1) efficiency.
Q 6 - Which of the below given sorting techniques has highest best-case runtime complexity −
Answer : B
Explanation
Selection sort best case time complexity is Ο(n2)
Q 7 - A queue data-structure can be used for −
Answer : C
Explanation
Queues can be used for limited resource allocation. For other operations, stacks are used.
Q 8 - In C programming, when we remove an item from bottom of the stack, then −
Answer : B
Explanation
Stack can only be accessed from top of it.
Q 9 - A balance factor in AVL tree is used to check
B - if all child nodes are at same level.
Answer : D
Explanation
The balance factor (BalanceFactor = height(left-sutree) height(right-sutree)) is used to check if the tree is balanced or unbalanced.
Q 10 - The worst case complexity of binary search matches with −
Answer : B
Explanation
In the worst case a binary search needs to access all elements of the target list, same as linear search.
